which it appertains to make and use same,

reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in electricalsignaling apparatus forrailway locomotives, etc., and consists in theprovision of various details of construction and combinations andarrangements of parts which will be hereinafter fully de-.

scribed and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a locomotive, showing the application ofmy invention. Fig. 2 is a diagrammatic view showing the electricalconnections with the axles of two locomotives, and Fig. 3 is adiagrammatic view showing the connections between the insulated axlesand the electric bell and bat- 'termediate track.

0 designates an axle section adapted to be mounted in suitable bearingsupon an engine and the outer end of said axle section O is connectedthrough suitable insulated collars C with the axle sections D. The axlesection 0 has a flanged wheel E fixed thereto, which travels upon theintermediate track B, and the axle sections D have wheels F which travelupon the outer rails A. Each axle section has a collar G loosely mountedthereon and a binding post G projects from said collar to which a wire His connected as shown clearly in Fig. 2 of the drawings. Said wires arein turn connected tothe binding posts 0 of the electric bell apparatus 0and to the battery Q. The apparatus upon either side of the intermediaterail is similarly connected electrically with a bell and battery, asshown in the drawings, and each engine is adapted to be provided withsimilar apparatus.

It will be noted that in Fig. 2 of the drawings, I have shown the axlesand apparatus representing two engines approaching from oppositedirections. In the apparatus at the right in Fig. 2, are the flangedwheels F traveling upon the rails A and the outer axle sections D uponwhich said wheels F are mounted, and to each axle section D is looselymounted a collar G to which a binding post is connected having securedthereto a wire 9, which in turn is connected to a binding post O thenceconnected to the battery Q. A second wire H is also connected to thebattery Q and leads to a binding ost upon a collar G upon the axlesection (i to which is keyed a flanged Wheel E running upon the middlerails B.

In tracing the circuit, the current leads from the battery Q through thebell apparatus O, thence to the collar G, to the outer axle section D,through the wheel F and outer rails A, to the outer wheel F of anapproaching locomotive, through the shaft D collar G to the bell Othence through one of the binding posts O to the battery Q and returningthrough the wire H to a collar G upon a shaft O thence through a wheel Erails B, to the wheel E, through the axle C, to the bell O and batteryQ. It will be understood that the electricity for furnishing the currentto the two approaching locomotives will be through the two batteries,each exerting its share of the electric force to cause the bells to bein circuit when the engines a proach each other near enough to form asuicient force to cause the alarms to be sounded.

WhatI claim is A signaling apparatus for railway locomotives comprising,in combination with three parallel rails, stub axles, bearing armsadapted to be supported by a locomotive and in which the inner ends ofsaid axles are j ournaled in suitable insulated bearings, stub axlesalso journaled in the outer ends of said bearings, wheels upon the stubaxles desame and the binding posts of said collars, as shown anddescribed.

In testimony whereof I hereunto afiix my signature in the resence of twowitnesses. GE RGE J. EXTERKAMP.

signed to travel upon the outer of said rails, a double flanged wheelmounted u on the intermediate of said stub axles and esigned to travelupon the middle of the track, collars mounted upon the stub axles, abinding post projecting from each collar, a setscrew fitted to eachbinding post, an electric signal, and circuit connections between the
